We all have mornings where we want nothing more than to stay in our beds, warm and comfortable, all day. If you’re having a morning like that, stoic philosopher Marcus Aurelius suggests you look to your true nature as a human being.

We are animals, living things that are a part of nature, no matter how smart and powerful we think we are. And as with all living things, it’s in our nature to go out and do. In Meditations, Aurelius writes:

At dawn, when you have trouble getting out of bed, tell yourself: “I have to go to work — as a human being. What do I have to complain of, if I’m going to do what I was born for — the things I was brought into the world to do? Or is this what I was created for? To huddle under the blankets and stay warm?”

So you were born to feel “nice”? Instead of doing things and experiencing them? Don’t you see the plants, the birds, the ants and spiders and bees going about their individual tasks, putting the world in order, as best they can? And you’re not willing to do your job as a human being? Why aren’t you running to do what your nature demands?

You don’t love yourself enough. Or you’d love your nature too, and what it demands of you.

You may not know your life’s purpose, or even believe in such a thing, but it’s hard to argue that lazing about in bed is the best way to spend your short time here. Aurelius believed people should spend their lives contributing to the betterment of the world, but at the very least, you can do something to better yourself. So, take a deep breath, hop out of bed, and go start your day. Succumb to your nature and go do.
